Systems and methods for fueling motor vehicles

ABSTRACT

Methods and systems can automate the delivery of motor vehicle fuel while reducing the need for operator involvement and driving to a gas station. A server with access to a database and in wireless communication with computers installed in a motor vehicle can collect data from the computers including vehicle fuel level and vehicle geographic location. The data can be compared to the data to a fuel level threshold and geographic boundary. The data can be transmitted wirelessly through a wireless network to the database. A mobile fuel tanker truck can be dispatched to the vehicle&#39;s location when at least one of: fuel service is requested by a user of the vehicle or the vehicle&#39;s fuel level falls beneath the fuel level threshold. Fuel service can be requested by a user via a smartphone running an application that enables the monitoring, management, selection, and ordering of fuel service.

INVENTION PRIORITY

The present invention claims priority as a continuation of ProvisionalPatent Application No. 61/896,273, entitled “Systems and Methods forFueling Motor Vehicles,” which was filed on Oct. 28, 2013, and is hereinincorporated by reference in its entirety.

FIELD OF THE INVENTION

Embodiments of the present invention relate to fueling motor vehicles,specifically to improved systems and methods for ordering, managing,refueling vehicles when a quantity of fuel in a fuel tank has beenconsumed, and further, to a mobile logistics system for refuelingprivate vehicles despite their location.

BACKGROUND

The fueling of motor vehicles generally relies on the presence ofstationary fueling sites (e.g., commercial gas stations, private fueldispensing sites). These fueling sites typically receive and store largequantities of fuel in onsite underground tanks. Fuel is delivered to thetanks by means of established supply chains involving refineries, bulksupply terminals, and fuel tanker trucks.

In a typical scenario, a motor vehicle in need of fuel must betransported to a stationary fueling site in order to refuel. Therefueling process involves exiting the vehicle, processing a form ofpayment, and manually pumping fuel from an underground storage tank tothe vehicle's fuel tank.

The refueling process, moreover, is widely considered to be adisagreeable experience. It requires a vehicle operator to take timeaway from other activities, travel to a designated location, brave theelements, and handle frequently used equipment. Fueling stations areoften dirty, tend to attract a disproportionate amount of crime, and cannegatively impact the environment. Even in the commercial fleet contextwhere private fueling sites are prevalent, the refueling process isproblematic. Vehicle operators are usually “on the clock” during therefueling trip and fleet managers often experience problems of fueltheft by both employees and nonemployees.

BRIEF SUMMARY OF EMBODIMENTS OF THE PRESENT INVENTION

In response to these concerns, there is a need to transform therefueling process itself. Present solutions fail to address a centralproblem: the need to physically transport a motor vehicle to astationary fueling site in order to refuel. There is thus a present needfor an improved system and method for refueling motor vehicles withouthaving to transport the vehicle to a fueling site. There is further aneed for a system and method that addresses the other shortcomings ofknown systems, including:

-   -   Eliminating the need for a vehicle operator to locate a        stationary fueling site within an acceptable distance from a        vehicle to be refueled.    -   Eliminating the need for the operator to locate a fueling site        that is pricing fuel at an acceptable level.    -   Eliminating the need for the operator to take time away from        other activities in order to transport the vehicle to and from        the fueling site.    -   Eliminating the need for the operator to brave the elements and        handle frequently used equipment.    -   Eliminating the need for the operator to expose himself or        herself to a dangerous environment.    -   Eliminating the requirement for the operator to patronize a        business that may negatively affect the environment.    -   Eliminating the need for a business owner to compensate an        employee-operator during the refueling of a fleet vehicle.    -   Eliminating the need for a fleet manager to guard against theft        and fraud associated with refueling.    -   Allowing for more flexible fuel pricing strategies (e.g.,        volume/time/location based pricing, spot-market and        futures-market based pricing).    -   Allowing for fuel price hedging opportunities.

A system in accordance with features of the present invention can takemany forms. In one embodiment, a system can be provided for automatingthe delivery of motor vehicle fuel wherein the need for operatorinvolvement is eliminated. Specifically, in one embodiment, a system canbe provided for collecting a vehicle's fuel and location data, comparingthe data to a fixed or variable geographic boundary, transmitting thedata through a network to an Internet-connected database, anddispatching a mobile fuel tanker truck to the vehicle's location.

In another aspect, this application can provide a system for placingone-off orders for the delivery of motor vehicle fuel. Specifically, oneembodiment can utilize a telecommunication technology, such as asmartphone within and/or otherwise associated with a vehicle and amobile software application installed on the smartphone. The applicationcan preferably monitor the vehicle's location, alert the operator whenthe vehicle is within range of mobile fuel service, and provide the userwith the ability to place a fuel order.

Another feature of the present invention can provide a system fordetermining a vehicle's fuel level and transmitting the information,which can optionally be done via a short-range wireless connection, to asmartphone located in and/or near the vehicle. A mobile softwareapplication installed on the smartphone can enable the delivery of fuelby uploading the information along with location data to anInternet-connected database.

Yet another feature of the present invention can provide a mobile meshnetwork. Specifically, there can be a system for transmitting andreceiving information between multiple vehicles, stationary networknodes, and a network coordinator.

In another aspect, the invention can provide a mobile geographicboundary. Specifically, there can be a system for varying a geographicboundary in connection with the location of a mobile fuel tanker truck;transmitting the changing boundary coordinates, and interacting with avehicle or a vehicle operator based on proximity.

In one feature, the present invention can relate to a system that allowsfor a more flexible approach to fuel pricing. In particular, the systemcan allow for continuous price adjustment based on situation-specificfactors (e.g., volume) and real-time market factors (e.g., spot prices).

In another feature of the present invention, fuel price hedgingopportunities are provided. Specifically, systems and methods can allowfor the purchase of fuel for future consumption, at present prices,using an online interface and a personalized fuel bank.

A method in accordance with features of the present invention canincorporate some, or all, of the following steps:

-   -   Determining a vehicle's fuel level;    -   Determining the vehicle's location;    -   Comparing the vehicle's location to a fixed or variable        geographic boundary;    -   Transmitting the fuel level and location data to an        Internet-connected database;    -   Analyzing the data in conjunction with other variables and        generating instructions;    -   Transmitting the instructions to a mobile fuel tanker trunk;    -   Driving the fuel tanker trunk to the vehicle;    -   Unlocking and/or opening the vehicle's fuel door;    -   Dispensing a quantity of fuel in the vehicle's fuel tank; and    -   Relaying the quantity of fuel consumed back to the database for        bill processing.

Aspects, advantages and novel features, and further scope ofapplicability of the present invention will be set forth in part in thedetailed description to follow, taken in conjunction with theaccompanying drawings, and in part will become apparent to those skilledin the art upon examination of the following; or may be learned bypractice of the invention.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows a schematic drawing of system 2 for automating the deliveryof motor vehicle fuel wherein the need for operator involvement iseliminated. Specifically, wireless appliance 3 including microcontroller4, GPS chipset 5, radio frequency transceiver 6, and serial connector 7plugs into on-board diagnostics (“OBD-II”) port 9 of vehicle 8. TheOBD-II port 9 is a 16-pin serial interface on all light-duty vehiclesmanufactured after 1996 and a 6-pin serial interface on medium andheavy-duty vehicles. The port 9 is typically located underneath thesteering column and provides access to the vehicle's engine control unit10, which monitors over one hundred vehicle parameters, including fuellevel. Fuel level is typically communicated to the engine control unit10 by means of an electric signal from the fuel level sensor (notshown). The fuel level sensor uses a variable resistor to change thevoltage of the signal in response to the movement of a mechanical floatlocated in the fuel tank.

In one embodiment, wireless appliance 3 preferably solicits fuel levelinformation from the vehicle's engine control unit 9 by determining theappropriate OBD-II communication protocol and broadcasting theappropriate parameter ID. The solicitation most preferably occursperiodically. When fuel level drops below an established threshold, GPSchipset 5 can activate and begin collecting radio frequency locationdata 11 from orbiting satellites 12 (in other embodiments, GPS chipset 5continually records location data 11).

Microcontroller 4 preferably compares the GPS data 11 to the coordinatesof a fixed or variable geographic boundary 13 stored in memory. If thevehicle is within geographic boundary 13, radio frequency transceiver 6can begin transmitting real-time fuel level and location data 14 tonodes 15 and 16 in a mesh network (in other embodiments, transceiver 6can broadcast data 14 more frequently or continuously). Nodes can bestationary transceivers positioned around geographic boundary 15 ormobile transceivers embedded in the wireless appliances of othervehicles participating in system 16. Nodes 15 and 16 preferably backhauldata 14 to network coordinator 17 serving as gateway. Networkcoordinator 17 uploads data 14 to the Internet. The data is preferablystored in an Internet-connected database managed by a host computer 18.Software running on the host computer 18 preferably causes the computerto analyze the data in conjunction with other variables 19 (e.g.,retail/spot/futures market prices, system load, inventory level) andapplies scheduling and pricing algorithms to generate instructions 20.

Instructions 20 can be transmitted to one or more mobile fuel tankertrucks 21 in communication with the host computer 18. The instructions20 may include, but are not limited to, driving directions, routingsequences, vehicle identity information, fuel grade information, andpricing information. An operator of tanker truck 21 preferably drives tothe location of vehicle 8, verifies the identity of vehicle 8, and opensthe fuel door and dispenses fuel into the fuel tank of vehicle 8. Somevehicles have either electronic or mechanical fuel door lockingmechanisms. In one embodiment, electronic mechanisms can optionally beunlocked by broadcasting the appropriate code from the wirelessappliance 3 to the OBD-II system. Mechanical fuel doors can optionallybe unlocked by means of a handheld apparatus inserted along the door'sedge. After fuel is discharged, the quantity of fuel consumed ispreferably recorded and relayed back to host computer 18 for billprocessing.

Communication between wireless appliance 3 and host computer 18 can alsorun in the opposite direction. Specifically, host computer 18 canoptionally transmit data through the network and back to wirelessappliance 3 for several purposes, including modifying the geographicboundary of the coordinates stored in memory, troubleshooting problems,and changing program settings (e.g., time delays and transmissionschedules).

FIG. 2 shows in more detail how fuel level and location data canoptionally be processed. Specifically, the FIG. 2 illustrates a flowchart of algorithm 30 used by the above-described system to solicit fuellevel data and initiate location gathering and data transmissionfunctions when appropriate. Steps 31 and 32 solicit vehicle fuel levelinformation and compare the information to a pre-determined threshold.If fuel level is above the threshold, the solicitation reoccurs after atime delay. If fuel level is below the threshold, step 33 activates theGPS receiver and begins collecting location data. While it is alsopossible for the GPS receiver to continually collect location data,selectively activating the receiver in this way may help address enduser privacy concerns. Steps 34 and 35 compare the GPS location data tothe coordinates of a geographic boundary. If the vehicle is not withinthe boundary, the comparison reoccurs after a time delay. If the vehicleis within the boundary, step 36 broadcasts the fuel level and locationdata over a radio frequency.

FIG. 3 shows a schematic drawing of a system 40 for placing one-offorders for the delivery of fuel. The system optionally relies on thepresence of a smartphone. 41 within or near vehicle 42 and uses thesmartphone's native hardware to receive and analyze GPS location data43. When a vehicle operator 44 drives within a fixed or variablegeographic boundary 45, a mobile software application (not shown) loadedin the operator's 44 smartphone 41 activates an alert message 46. Thealert message 46 prompts the operator 44 to visually check the vehicle's42 fuel level 47. If fuel level 47 is low, operator 44 can place a fuelorder—optionally this can be set to occur when vehicle 42 is parked.When a fuel order is placed, smartphone's 41 cellular radio preferablytransmits location data to an Internet-connected database managed byhost computer 48. As in the previous embodiment, software on hostcomputer 48 accesses other variables 49, then generates and transmitsinstructions 50 to mobile fuel tanker truck 51.

There are multiple alternatives to the system illustrated in FIG. 3. Forexample, a simpler version of the wireless appliance described above caninclude no GPS chipset and can replace the radio frequency transceiverwith a Bluetooth radio. The appliance can optionally determine fuellevel as described above, and then transmit the fuel level data via theBluetooth radio to a smartphone located in and/or near a vehicle. Asoftware application in the smartphone can automatically upload the fuellevel data, along with location data derived from the smartphone's GPSchipset, to an Internet-connected database. The system can automate thedelivery of fuel or require involvement from the vehicle operator.

FIG. 4 shows a table 60 listing some method steps 61 along withpotential system components 62 that can be used to accomplish steps 61.The purpose of table 60 is to provide an overview of the various optionsavailable for piecing together a working system.

FIG. 5 illustrates a schematic drawing of mesh network 70 in operation.Specifically, the drawing shows how mesh network 70 can be used toenlarge a fuel delivery service area without the need to installstationary network nodes 71 throughout the entire service area. Threezones are illustrated: a residential center 72, an employment center 73,and a retail center 74. The residential center 72 and the employmentcenter 73 are surrounded by stationary network nodes 71, while theretail center 74 is not. Vehicle 75 is driving from the residentialcenter 72 to the employment center 73. Vehicle 76 is driving from theretail center 74 to the residential center 72. Vehicle 77 is parked atthe retail center 74 and is low on fuel. Vehicles 75, 76, 77 are allequipped with wireless appliances (not shown) as described above.

In a traditional hub-and-spoke or star network topology, vehicle 77would have to be within range of a network coordinator 78 in order totransmit fuel level and location data to a host computer 79. Because theretail center is out of range of retail center 74, vehicle 77 could notbenefit from the fuel delivery system described above. However, byembedding mobile transceivers in the wireless appliances of vehiclesparticipating in the system and by using a mesh network 70 topology, itis possible to gain awareness of the fuel level of vehicle 77 and itslocation data despite the fact that vehicle 77 is out of range.Specifically, the data of vehicle 77 preferably propagates throughnetwork 70 by means of other vehicles participating in the system. Datatransmission can occur as follows: vehicle 77 to vehicle 76, vehicle 76to vehicle 75, vehicle 75 to stationary network node 71, stationarynetwork node 71 to network coordinator 78, network coordinator 78 tohost computer 79, host computer 79 to fuel tanker truck 80.

Using a mesh network 70 with mobile transceivers is advantageous forseveral reasons. First, the production cost of wireless appliances canbe minimized (e.g., shorter-range radio frequency transceivers are muchless expensive than cellular radios). Second; data transmission canoccur across a wide geographic area without relying on access toexpensive global system for mobile communications (“GSM”) networks andcode division multiple access (“COMA”) networks (i.e., users will nothave monthly data usage fees). Third, network deployment costs can beminimized by reducing the need for stationary network nodes. Fourth,network coverage reliability will continue to increase as more usersparticipate in the system.

FIG. 6 illustrates a schematic drawing of system 90 for varyinggeographic boundary 91 in connection with the location of mobile fueltanker truck 92. Specifically, mobile fuel tanker truck 92 uploadsreal-time location data 93 to an Internet-connected database managed byhost computer 94. Software running on the host computer 94 createsdefined geographic boundary 91 around truck 92. If boundary 91 is acircle, it may be defined by a latitude/longitude coordinate pair and aradius of a given distance. Host computer 94 transmits coordinates 95 ofboundary 91 through network 96. Depending on system architecture,boundary coordinates 95 may be transmitted to a wireless appliance (notshown) as described above and/or to a mobile application running on auser's smartphone (not shown). If the appliance or smartphone is withinboundary 91, system 90 can interact with a vehicle or vehicle operatorin numerous ways, including: dispatching fuel service to a vehicle,generating an alert message on a smartphone, and sending an email to aregistered user.

FIG. 7 illustrates some potential inputs to fuel pricing algorithm 101.Specifically, it illustrates situation-specific factors 102 andreal-time market factors 103 that can be incorporated into the algorithmto generate a fuel price. Currently, in the context of stationaryrefueling sites, it is impractical to adjust fuel prices in real-time.With a fuel delivery system as described above, a host computer can makeautomatic and instantaneous price adjustments based on numerous factors.

FIG. 8 illustrates a schematic drawing of a web-based orsmartphone-based interface 111 for fuel price hedging. In rising fuelprice environments, a typical vehicle operator is unable to stockpilelarge quantities of gasoline for future consumption. The systems andmethods presented in this application allow for the purchase of aquantity of fuel, for future consumption, at present prices.Specifically, a vehicle operator can log into interface 111, select fuelgrade 112 and quantity 113, and complete a fuel purchase at currentmarket prices 114. Fuel quantity 113 of purchased can be then added toan operator's individual fuel bank 115. Future fuel deliveries to thevehicle operator will subtract from the fuel in the operator's fuel bank115 and will be priced at the average price per gallon 116 of all fuelin the fuel bank 115. When a host computer (not shown) receives a fuelbank purchase 117 from a vehicle operator, the computer can initiate acorresponding and instantaneous spot market purchase to “lock in” priceand ensure availability.

In one embodiment, the motorized vehicle does not include aircraft. Inone embodiment, the motorized vehicle is a passenger vehicle. In oneembodiment, the motorized vehicle is a fleet vehicle. In one embodiment,the motorized vehicle is a vehicle which is included within the FederalHighway Administration's thirteen-category classification scheme,including: motorcycles, passenger cars, pickups, panels, vans, buses,and two-to-six-axle trucks. In one embodiment, the motorized vehicle isnot a land-based vehicle. In one embodiment, the motorized vehicle is aboat. In one embodiment, the vehicle is an aircraft.

In one embodiment, the invention relates to a system for determininglocation information by sending request messages and receiving responsemessages. Specifically, any participant in the system (e.g., aland-based computer, cloud-based computer, wireless appliance,smartphone, fuel tanker truck appliance, or third party monitoringagent) can be configured to initiate communication with any otherparticipant in the system in order to solicit location information. Therequest message can be sent at periodic intervals and the responsemessage can optionally be programmed to include GPS coordinates.

In another embodiment, a vehicle without a built-in wireless appliancecan be located by tracking a vehicle operator's smartphone.Specifically, smartphone GPS coordinates can be periodically transmittedto a host computer in response to a communication received fromtherefrom, or as part of a smartphone-initiated transmission. Softwareinstalled on the host computer can cause the computer to use thecoordinates to pinpoint the smartphone's location and analyze the changein coordinates over time to determine velocity. Significant changes invelocity can be analyzed to determine when the vehicle operator exitsthe vehicle (for example, the system can determine when a user is likelywalking away from the vehicle because the cell phone that the user iscarrying on his or her person is transmitting coordinates over timeintervals that are consistent with a walking speed and not with avehicle driving speed). Coordinates can then be “tracked back” from thecontinuing low-velocity path to the last known high-velocity location toidentify where the vehicle is parked.

In one embodiment, the present invention relates to an automated fueldelivery system. Determination and communication of a user's need forfuel and the user's vehicle location can be achieved automatically innumerous manners. The present invention thus relates to any and allmanners of wirelessly transmitting a vehicle's fuel level and locationinformation to an external computer for the purpose of determining theproximity of a mobile fuel tanker truck and dispatching the tanker truckto refuel the vehicle.

In another embodiment, software running on a host computer can apply analgorithm to intelligently route a fuel tanker truck to a targetvehicle's location. Specifically, the host computer can analyze thechange in a target vehicle's location over time so as to determinewhether the target is parked, moving, entering a service range, orexiting a service range. Multiple data points can be used to refine thealgorithm, including historical travel patterns, time of day, averagestationary time at known locations (e.g., shopping centers),combinations thereof, and the like.

In one embodiment, the present invention can include the ability tounlock fuel doors on vehicles for purposes of adding fuel to thevehicle's fuel tank when the vehicle owner is not present to unlock orotherwise open the fuel door. In this embodiment, if a tanker truckoperator arrives at an unmanned vehicle that has a locked fuel door, anelectronic signal or handheld apparatus can be provided to unlock and/oropen the fuel door. For vehicles which have electronic locking fuel doormechanisms, such doors can optionally be unlocked by broadcasting theappropriate code from the wireless appliance to the OBD-II system. Forvehicles which have mechanical locking fuel doors, such doors can beunlocked by with a handheld apparatus inserted along the door's edge.

Optionally, embodiments of the present invention can include a generalor specific purpose computer or distributed system programmed withcomputer software implementing steps described above, which computersoftware may be in any appropriate computer language, including but notlimited to C++, FORTRAN, BASIC, Java, assembly language, microcode,distributed programming languages, etc. The apparatus may also include aplurality of such computers/distributed systems (e.g., connected overthe Internet and/or one or more intranets) in a variety of hardwareimplementations. For example, data processing can be performed by anappropriately programmed microprocessor, computing cloud, ApplicationSpecific Integrated Circuit (ASIC), Field Programmable Gate Array(FPGA), or the like, in conjunction with appropriate memory, network,and bus elements. One or more processors and/or microcontrollers canoperate via instructions of the computer code and the software ispreferably stored on one or more tangible non-transitive memory-storagedevices.

Although the invention has been described in detail with particularreference to these preferred embodiments, other embodiments can achievethe same results. Variations and modifications of the present inventionwill be obvious to those skilled in the art and it is intended to coverall such modifications and equivalents. The entire disclosures of allreferences, applications, patents, and publications cited above and/orin the attachments, and of the corresponding application(s), are herebyincorporated by reference.
